Thanks for the guidelines, but basically our idea is to build a
system like
http://del.icio.us/tag/, is it possible to take counts of similar
words from
a solr indexed field?
How do you define similar words?
Here's a tag cloud for a single user in Collex, a system I built:
<http://www.nines.org/permalink/cloud/tag/nowviskie>
Collex is using SOLR-139 now for tagging/annotating.
You will need to think through handling updates to your documents,
and whether you will have user-specific tags too. Reading up on the
links I sent you and doing some experimenting is highly recommended.
It's a non-trivial scenario with Solr at this time.
By the way, a del.icio.us competitor, Simpy, is built on Lucene - so
it is quite possible to build a heavy duty tagging system, but the
devil is in the details.

We are running an appalication built using SOLR, now we are trying
to build
a tagging system using the existing SOLR indexed field called
"tag_keywords", this field has different keywords seperated by
comma, please
give suggestions on how can we build tagging system using this
field?
There is also a wiki page on some brainstorming on how to implement
tagging within Solr: <http://wiki.apache.org/solr/UserTagDesign>
It's easy enough to have a tag_keywords field, but updating a single
tag_keywords field is not so straightforward without sending the
entire document to Solr every time it is tagged. See SOLR-139's
extensive comments and patches to see what you're getting into.
